210115_114630 144.174 Rx FT8 -17 -1.6 685 SIDE LOBE This is probably the one real one of the bunch, actually! The odds of random noise decoding as a freetext message with sensible English in it are vanishingly small. This was probably from someone who worked someone on 2m FT8, and then after exchanging their grid squares, sent a followup message to ...

I'd say these are simply corrupt. Take for example: 210113_163545 144.174 Rx FT8 -17 1.3 1247 J06NQY A68ITS/R R QM30 A68ITS doesn't seem to be a real call, but if it was, it would be a UAE call. The grid QM30 is in the Pacific ocean, about 800 km off the coast of Japan. This is a pretty unlikely combination. The FT8 protocol includes error correction ...

It is presumed that you were receiving on the 2m band. It appears that you were listening in, using 'repeater reverse' mode. In other words, you were listening in on the repeater's input frequency rather than on it's output. On 'reverse', you would hear all the stations within range. In this case only one station would have been within range. Had you ...

No. Yes. There's no particular reason to think so. The UK and the US have both adopted CEPT T/R 61-01 regarding reciprocal amateur operation. Despite the fact that CEPT is the "European Conference of Postal and Telecommunications Administrations", it's independent of the EU (it long predates the EU), and parties to T/R 61-01 don't have to be ...

The US has no specific reciprocity agreement with the UK, but both countries have adopted CEPT T/R 61-01, which is what allows reciprocal operation between them. Only the UK full license is regarded as equivalent to a CEPT license; Foundation and Intermediate don't count for anything.

The concept is called "offset". The repeater is listening on one frequency, and is repeating it verbatim in real time on another frequency, but typically at a higher power so more people can hear it further away. Most repeaters (numbers specific for the US anyway, but the concept applies internationally) have a plus or minus 600 khz offset. This is not a ...
